ANTISLIlP-CLEA'I.

Specification of Letters Patent.

Patented Sept. 17, 1912.

Application filed April 6, 1910. Serial No. 553,836.

To all whom it may concern: I

Be it known that I, GEORGE L. PIERCE, a citizen of the United States,and resident of Brooklyn, county of Kings, city and State of New York,have invented certain new and useful Improvements in Antislip- Cleats,of which the following is a specification.

The advantages of my improved cleat are that the adaptation of the baseplate to the ground-entering parts is such that the cleat has maximumstability on the shoe with minimum liability to tear off, and that theground-entering parts are designed to offer minimum resistance toentering and leaving the ground without being dangerously sharp. Theseand other advantages will appear from an understanding of thedescription and drawings. Furthermore, it is not essential that all ofthe features of advantage shall be combined in the same device although,of course, that is desirable.

In the drawings, Figure 1 is a view of the underside of a shoe, forexample a base ball shoe, showing toe and heel cleats with my inventionsecured thereto, and Fig. 2 is a sectional View partly in elevation onthe line 2-2 in Fig. 1 looking in the direction of the arrows.

I will now describe the devices of the drawings, reserving it to theclaim to point out the novel features and to define the scope of theinvention, it being understood that the claim will be given due range ofequivalents.

The cleats will be made of any suitable materials, such as malleableiron. Moreover, the ground-entering parts may be integral ornon-integral with the base and may be hardened or otherwise. The baseplate 1 of the cleats may take triangular form with a ground-enteringpart 2 at each corner of the triangle. For the sake of lightness withoutsacrifice of strength, the base plate 1 has an open central portion 3bridged across by a web 4 integral with the inclosing sides of thetriangle. Thus, the web 4 permits the open center to be as large aspossible and the weight of the base plate to be reduced to a minimumwithout sacrificing any necessary strength.

The ground-entering parts 2 have blunt entering tips 2 on the free endsof the shanks 2 which in turn are secured by their bases 2 to the baseplate, said shanks between their bases 2 and their free ends having asubstantially uniform cross section, preferably cylindrical as shown,although the sides of the shanks may curve inwardly. The result of thispreferred construction of ground-entering part is that without beingsharp and therefore dangerous, it nevertheless ofi'ers little resistanceto entering and leaving the'ground, because this resistance is for themost part confined to the head 2 whereas the shank, once the head hasentered, offers little resistance since for the most part it is ofsubstantially the same diameter as the entering end of the shank and maybe of less diameter.

Another feature of the cleat shown is the increased stability of thecleat on the shoe and the security of its attachment to the shoe,brought about by locating the groundentering parts at a distance backfa'om the corners of the base plate as distinguished from locating themsnugly in the corners with no substantial portion of the base plateprojecting beyond. Thus, referring to the drawings, it is preferred tohave enough of the base plate projecting at the corners beyond theground-entering devices to provide for outside rivet holes 5 in additionto the inside rivet holes 6 on the opposite side of the ground-enteringparts. In Fig. 1, 7 designates the clenched heads of the rivets 8 thatsecure the cleats to the shoe.

The reason why the cleat shown, with the corners of its base plateprojecting beyond the ground-entering parts remedies one of thedifficulties of devices of this descrip tion,tearing away from theshoe-will now be apparent. In the first place, the ground -enteringparts have a supporting base on both their inner and outer sides, and inthe second place, provision is hereby made for riveting or otherwisesecuring the base plate by points of attachment on opposite sides ofeach ground-entering part. In short, the improved cleat combines thequalities of lightness and strength, great stability in attachment tothe shoe, and minimum resistance to entering and leaving the groundwithout being sharp or dangerous.

What I claim is:

An anti-slip cleat for shoes, comprising a base plate of generallytriangular shape and having an open center and a transverse web bridgingthe same, a plurality of groundentering parts, one being located at eachcorner of the base plate and being disposed between the inner outermargins thereof, Witness my hand this fourth day of April and sets offastening devices for securing 1910, at New York city, N.
